Slang for when a girl/women fingers/ uses a sexual toy on her
vagina whilst "
wet". This is because it is the comical 'sound' a
vagina makes while under pleasure/ "wet".
Yea, I bet she enjoys a bit of a splitch every now and then.
She splitched herself last
night, maybe she was
lonely.
I was woken up by my mother's spltiching last
night.
